Last Name on Kesubah
Question: Should the last names of the chasan, kallah, and witnesses be written on the kesubah?
Short Answer: Although Rav Moshe Feinstein zt”l, Rav Yosef Shalom Elyashiv zt”l, and Rav Yosef Dov Soloveitchik zt”l all thought it preferable to include the last names on the kesubah, the prevalent custom is not to include last names.
